f 00% whom it may concern:

Be it known that I, L. LEWIS SAGENDORPl-I, of the city of Cincinnati, inHamilton county and State of Ohio, have invented certain new and usefulImprovements in Corrugated Iron Roofing, of which the following is aspecification.

The object of my invention is to provide a new and improved joint forcorrugated iron roofing, by which a saving of material is effected atthe same time that a more perfect and durable joint is made.

The various features of my invention, and the advantages resulting fromtheir use when applied together, or when one or more of said featuresare applied without the remainder, will be fully apparent from thefollowing description and claims.

Referring to the drawings forming part of this specification, Figure lis a perspective View showing three sheets of corrugated roofing. Fig. 2is a sectional view of the same. Fig. 3 is an enlarged section showingthe joint between two sheets and the preferred means for connecting thesheets to the roof. Fig. 4 is a view in perspective of a portion of acorrugated sheet having a half-V crimp, provided with slits forreceiving a cleat, applied in the preferred manner of my invention. Fig.is

a perspective view of the lower or under side ofa sheet, showing the endcleats or tongues for making a secure joint between the ends of thesheets. Figs. 6 and 7 are views illustrating the form of corrugated ironroofing and the manner of connecting it to the roof as heretoforeemployed.

These latter figures are shown to enable me to more clearly define myimprovements.

As ordinarily constructed, the sheets A are evenly corrugated from sideto side, the corrugations at the edges of the sheet being in allrespects similar to those throughout the remainder of the sheet, andwhen the sheets are laid on the roof M the corrugation at the edge ofone sheet is caused to overlap the corrugation at the edge of theadjoining sheet, as shown in Figs. 6 and 7, and a nail, n, is driventhrough these lapping edges into the roofboards. Theobjection urged tothis joint is that the water soon works up under the over- I prefer touse my invention in connection with such roofing as is hereinafterdescribed, viz: The body of the sheet is corrugated, as in the old styleof roofing. One edge of each sheet is provided with a V-crimp, B, andthe other edge of each sheet has a flange or half-V crimp, 0, turned ata right angle, or approximately such an angle, to the plane of thesheet. Then the sheets are laid onv the roof. The V-crimp at one edge ofa sheet is placed over the half- V crimp or flange of the adjoiningsheet, and a pair of roofing-tongs is caused to grasp the V-crimp andflange, which are pinched tightly together, and this joint projectsvertically from the plane of the roof, and consequently no water canwork through, as in the other style of corrugated roofing jointhereinbefore described.

My invention relates to means for securing the sheet to the roof. Thesheets may be cor rugated or otherwise.

For the purposes of illustration, I have, in

Figs. 3 and 4., shown my invention as applied to corrugated sheetingprovided with a V- crimp, substantially such as hereinbefore described.

Atintervals of p referably about one to three feet along the flange C,and near its upper edge, are a number of openings or slits, m, therein,and through each one of these slits m is respectively passed a cleat, D,one end, a, of which cleat is bent down and secured to the roof, usuallyby nailing it thereto, as shown in Fig. 3. down, as shown, to allow theV-crimp of the next sheet to slip down over the flange and the cleats,after which the end (2 of the various cleats is bent over the V-crimp,as shown in Fig. 3, and the V-crimp, flange,'and each cleat are thentightly pinched together, making a tight joint and securing theadjoining edges of the two corrugated sheets to the roof.

The portion b of the cleat is bent If desired, instead, of passing thecleats D through slits in the flange 0, they may be bent over the top ofthe flange; but I prefer to introduce the cleats through the flange, asthey will then prevent any longitudinal movement of the sheets.

Another feature of my invention is as follows: In order to make ainoreperfect j oint between the ends of the sheets, I secure to the underside of one end of each sheet (preferably to that end which is tooverlap the adjoining sheet) a number of short strips or cleats, E, (seeFig. 5,) one end of said strips extending to or a little beyond the endof the sheet, the opposite end only of said strips being secured to thesheet. The first sheet having been laid and secured to the roof, thelower end of the adjoining sheet is caused to overlap the first sheet,the ends of the cleats being slipped under the upper end of the firstsheet, thus uniting the adjoining ends of the sheets.

Having thus described my invention, what I claim as new and of myinvention, and desire to secure by Letters Patent, is-

1. In a metal roof, the corrugated sheets A, one sheet being provided atone edge with a \l-crimp overlapping the flange O of the adjacent sheet,said flange being provided with an opening or openings, on, incombination with a cleat or cleats, D, one end, a, of the cleat beingsecured to the roof, and the cleat then passing up between the V-crimpand the flange, thence through slit m, then down between the flange and\/-crirnp, thence around the edge of the crimp, and up over and aroundthe crimp, substantially as and for the purposes specified.

2. "In a sheet-metal roof, the sheets A, one end of each sheet beingprovided with the cleats E, secured to the under side thereof 0 near oneend, the end of said cleats being adapted to slip under the end of anadjoining sheet, substantially as and for the purposes specified.
